Lesson Plan

Lesson: 3-6
Title: How can work be measured?
Objective: Teach class how to measure in newtons.
Tech Term: Joule (Jool) metric unit of work, equal to 1 n-m.
Anticipatory Set: Ask for a volunteer. Ask them to move 2 newton cubes 5 meters. Ask them to guess how much work force they just made. Tell them you just made 10 n-m.
Question: what is a Newton?
Answer: It's a unit of measurment. 1 Newton is equal to 100 grams or
25 lbs is 4 Newtons.
“A Newton is a unit of weight unit.” So, today were going to be working with Newton’s. We’re going to teach you on how to measure work.
Step by step instructions:

  1. Get materials (Newton cube, scale, meter strip).
  2. Measure about 2-3 meters off ground.
  3. Hook cube to scale.
  4. Put scale close to ground so that the cube rest on the ground.
  5. Lift scale & cube up off the ground to designated mark.
  6. Record on paper how many meters you moved the cube.
  7. Do it again 2 or 3 times.
  8. Now take the number of meters times the number of newtons you moved.
  9. The answer is the amount of work force you just made.
Guided practice: Do steps above.
Closure: “So this is how you can measure your work force if you ever need to later in life. You have to measure it in n-m so it’s accurate.
Assessment: Easy Test
Extensions: None.
Materials: Newton cube, scale, meter stick.
